The ozone turns the processing to affect to the mineral spring fluid matter
provenance:China Mineral Water  Date

- In the last few years, the our country mineral the production of the spring practice, making people know to drink the natural mineral spring of production more difficult than general beverage, its reason is the mineral spring, product can't add the antiseptic, can't heat put out the germ and the living creature index sign to request to attain" double zero". therefore the microorganism pollution the problem has been perplex the mineral spring produce the factory house, to solve the microorganism pollution problem must adopt the system engineering, include the headwaters, environment, technique equipments and manage a series of problem of etc., among them most how the problem of the key is the disinfection put out the germ. resolve the mineral spring in the method of the germs have two kinds of:(1) the physics method: the adoption film filter the technique, wanting ¡«only the film of bore path small in the germs diameter, this kind of film can availably the slip away the germs;(2) the chemistry method: adoption the ultraviolet ray and ozone disinfect put out the germ, among them ozone disinfection is currently domestic and international mineral spring production line application most widespreadly put out the germ disinfection method.
-1. the ozone disinfect
-1.1 ozones disinfect in water handle of application
- The ozone have used for disinfect processing for very long,19 centuries, end someone carries on the drinking processing with the ozone in the beginning, there is already more than 500 ozones processing factory in Europe of middle of 70's, arriving to already have more than 3000 factories of water currently use ozone processing drinking. domestic and international the food industry includes the mineral spring production also extensive applied ozone disinfect put out the poison.
-1.2 characteristics of the ozones
- The ozone is an unsteady air of baby blue, dissolve in the water but fuse one degree small. the ozone oxidizes to restore the only next to fluorine(2.87 Vs) of electric potential(2.07 Vs), but high in chlorine gas(1.97 Vs) and carbon dioxide(1.5 Vs), it is a kind of strong oxidizing agent and the disinfection: the stability of the ozone is bad, will fuse the aqueous solution of the ozone to place, the density of the ozone will prolong but descend along with time that place. someone experiment: be 20 ¡æs of indoor temperature, the PH of the ozone water is 7.6,10-15 ¡æs of water temperature, draw the density of the ozone water along with the curve that time change, measure its half- life as 36 minuteses, because of the ozone half- life short, be easy to the decomposition, did not remain the thing in the water, so be applicable to the disinfection of the mineral spring, drinking, beverage, food...etc..1.3 ozones put out the germ result ozone aqueous solution to have to disinfect the function very strongly, the density need is low, the function is quick. be its density to attain the 2 mgs/ L or so, function a minute, can kill the bud afterbirth, black song mildewed, leaven of the E. coli, golden color staphylococcus, germs etc. microorganism. actually as long as the ozone density attains the value of , can kill microorganism to put out in cutty time, this value is different to the microorganism of different category. for example the fungi is a 1.5 mgs/ L, the germs propagule is a 3 mgs/ L.
- Take the natural mineral spring to expose it in in the air, let natural growth of germs. then hereat the kind of water opens into the ozone air of different density, distinguish in get in touch with 5 minutes and closeness to place 24 hours behind measurese the germs of density( see the table 1). be the aquatic ozone density of the mineral spring to attain the 0.5 mgs/ L, can kill all of the germses to put out within 5 minutes. |
